    "Magic Potion! My menopausal skin crisis happened just as this product was launched. My skin was suddenly reacting to products I had used for months/years. It was red, dry, flaky and thick. I took a chance and bought the Ectoin Hydro-Barrier Serum to see if it would help. It did an amazing job of calming my skin."

    Great barrier serum

    This serum is great for my dehydrated sensitive rosacea prone skin, doesn’t irritate and keeps it calm and hydrated and healthy. Only need to use a small amount too.

    Smell can be improved

    I just started using this after the black Friday sale, and I think it makes a difference, but what I have trouble adjusting to is the smell 😞.
